	Miscellaneous changes made after a review against the POSIX spec.
	* posix/src/pbarrierinit.c, posix/src/prwlockinit.c: If the caller
	passes a NULL in the attributes parameter, default attributes are used.
	* posix/src/prwlockdestroy.c: If there is at least one thread
	waiting, do not allow deletion.
	* posix/src/prwlockwrlock.c: Corrected parameter passed to the core
	operation used to obtain a RWLock for writing.
	* posix/src/pspinlocktranslatereturncode.c,
	score/include/rtems/score/corespinlock.h,
	score/src/corespinlockrelease.c: If the current thread is not the
	holder of the lock, do not allow an unlock and return EPERM.
	* score/src/corerwlockobtainwrite.c: Corrected to use the operation
	for queueing with a timeout handler.
